Just got a new GMC rcsb 2wd (750mi); mods just started. Past weekend installed an Extang flip-up soft tonneau. Yesterday had the tuner disable the AFM, rework shifts/firmness in the 6L80, and reset efans to come on sooner. Next week comes rear susp 3" drop and some Llumar on side windows before summer heat hits! Performance mods really begin with CAI, Kooks and custom 304SS catback, followed by aftermarket heads/cam. Add'l "stuff" after that.


Update: 3" susp drop arrived yesterday, CAI arrives tomorrow, and the Kooks have been ordered (waiting for the Jet Hot on them)... the Llumar was "fastened" this morning.

 

Welcome back!!! What are the goals! nice turck!!
